Extruder Compatible-OMG V2S Packing list: 1set= 2pcs
Heat treatment 60HRC 4 miniature bearings High speed-0.5 die - 48 teeth Filament gear diameter 8.4mm
E-STEP If using a 42 stepper motor, the step angle is 1.8°, the motor drive is 16 subdivisions, and the gear ratio is 1:3 E-STEP 363
If ​​using a stepper motor at 36 pitch, the pitch angle is 0.9°, the motor drive is 16 subdivisions, and the gear ratio is 1:3 E-STEP 726
1-spring presses filament pressure 2-and material of soft and hard filament E-step value should be tested and adjusted after installation
 
E-step: calculation method Use 1/16 subdivision motor, Stepper motor step angle = 1.8°, The diameter of the gear is 8.4mm, the stepper motor needs 16*200=3200 signals ofimpulse to turn 360°, Filament moving length = gear circumference = 3,d = 3.14*8 = 26.376mm How much e-step = filament displacement 1mm: Calculation method: 3200/26.376 = 121 pulse signal. E-step value is 121 Gear ratio is 1:3 - E-step value needs 3 times, that is 127.39*3=363 (theoretical value) If you use 0.9° step angle - the electronic step value needs 2 times, that is 363*2=726 (theoretical value)
